Gas Leakage Inspection
Please use gas leakage detector to check if leakage occurs
at the connection of Flare nut as shown on the right.
If gas leakage occurs, further tighten the connection to stop
leakage.

Preparation of Pipe
1
●
Use a pipe cutter to cut the copper pipe.
●
Jagged edge will cause leakage.
●
Point the side to be trimmed downwards during trimming to prevent copper
chips from entering the pipe.
●
Before
fl
aring, please put on the
fl
are nut.

WARNING
●
If you cannot attach the side plate due to the connecting
cord, press the connecting cord in direction to the front
panel to
fi
x it.
●
Be sure that the hooks of the side plate is
fi
xed in certainly.
Otherwise water leakage may occur and this causes short
circuit or faults.
Checking for the electric source and the
voltage range
●
Before installation, the power source must be checked and necessary wiring work
must be completed. To make the wiring capacity proper, use the wire gauges list
below for the lead-in from a pole transformer and for the wiring from a switch
board of fuse box to the outlet in consideration of the locked rotor current.
●
Investigate the power supply capacity and other electrical
conditions at the installation location.
Depending on the model of room air conditioner to be installed,
request the customer to make arrangements for the necessary
electrical work etc.
The electrical work includes the wiring work up the outlet.
In localities where electrical conditions are poor, use of a
voltage regulator is recommended.
●
Install outlet for the room air conditioner within the reaching
range of the line cord.
●
THIS APPLIANCE MUST BE EARTHED.

To remove the connecting wires for
the indoor unit, please remove the

Wiring Of The Indoor Unit
●
For wire connection of the Indoor unit, you need to remove front panel and
electrical cover.
Method to remove front panel
●
Please refer to Instruction Manual – “Removing the Front Panel” under “Cleaning
of Front Panel”.
●
The naked part of the wire core should be 10 mm and
fi
xed to the terminal tightly. Then try
to pull the individual wire to check if the contact is tight. Improper insertion may burn the
terminal.
●
Be sure to use only power cables approved from the authorities in your country. For example
in Germany: Cable type: NYM 3x1.5mm
2
, (fuse = 16A time delay)
●
Please refer to the following for wire connection to the terminals of the units. The cabling
must meet the standards of electrical installation.
●
There is a AC voltage of 220~230V between the L and N terminals. Therefore, before
servicing, be sure to remove the plug from the AC outlet or switch off the main switch.

Fully tighten the “Hi” knob of the manifold
valve and completely unscrew the “Lo” knob.
Run the vacuum pump for about 10~15
minutes, then completely tighten the “Lo” knob
and switch off the vacuum pump.

Completely unscrew the spindle of the
service valve (at 2 places) in anti-clockwise
direction to allow the
fl

Hexagonal Wrench key).
Re-cap the service valve and tighten using
wrench. Check the cap’s periphery if there is
any gas leakage. The task is then completed.
Remove the charge hose and tighten the cap
of valve core. Check the cap’s periphery if
there is any gas leakage.

OUTDOOR UNIT
●
Please mount the Outdoor unit on stable ground to prevent
vibration and increase of noise level.
●
Decide the location for piping after sorting out the different
types of pipe available.
●
When removing side cover, please pull the handle after undoing
the hook by pulling it downward.
Please face this side (suction side)
of the unit to the wall.
Please remove side cover
when connecting the piping
and connecting cord.
Please make sure to remove all spacers inside the unit.
●
Open the Top, Back, Side cover and Cabinet of the unit.
●
Pull out the spacers inside.
(Spacers are only for transportation purpose).
If not remove, vibration and noise will occur.

Insulation And Maintenance Of Pipe Connection
1
●
The connected terminals should be completed sealed with heat
insulator and then tied up with rubber strap.
●
Please tie the pipe and power line together with vinyl tape as
shown in the
fi
gure showing the installation of indoor and outdoor
units. Then
fi
x their position with holders.
●
To enhance the heat insulation and to prevent water condensation,
please cover the outdoor part of the drain hose and pipe with
insulation pipe.
●
Completely seal any gap with putty.
Installation Of Remote Controller
2
●
The remote controller can be placed in its holder which is
fi
xed
on wall or beam.
●
To operate the remote controller at its holder, please ensure
that the unit can receive signal transmitted from the controller
at the place where the holder is to be
fi
xed. The unit will beep
when signal is received from the remote controller. The signal
transmission is weaken by the
fl
orescent light. Therefore, during
the installation of the remote control holder, please switch on the
light, even during day time, to determine the mounting location
of the holder.
The controller should
be insert from top into
bottom side of the
holder as shown in
fi
gure beside.
